BLnNmne-srnAYER.

Application filed September 11, 1919.

To all whom it may concern:

Be it known that I, Josnrrr B. SI-Innvn, a citizen of the United States, residing at Quay, in the county of Pawnee and State of Oklahoma have invented certain new and useful Improvements in a Blending-Sprayer of which the following is a specification.

This invention has for its object to provide an improved sprayer for use in the manufacture of volatile liquids such as gasolene by which the blending fluid is sprayed in a light mist or vapor.

Another object is the provision of a device of this character embodying novel features of adjustment whereby a series of spray ports may be conveniently controlled to regulate the quantity of liquid dlscharged from the sprayer.

With these and other objects in view as will appear as the description proceeds the invention comprises the novel features of construction combination of elements and arrangements of parts which will be more fully described in the following specification and set forth with particularity in the claims appended hereto.

Figure 1 represents a side elevation of the improved sprayer.

Fig. 2 represents a longitudinal sectional view therethrough.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views the numeral 5 indicates a hollow cylindrical barrel provided with a medially enlarged and externally threaded portion 6 for reception within a suitably internally threaded aperture formed in a portion of the machine to which the sprayer is applied. The internal bore of the barrel 5 is formed with internal screw threads 7 which extend inwardly from one terminal of the barrel to a point adjacent the screw threads 6 and toward the opposite end of the barrel the bore is restricted as indicated at 8 and is provided with a plane inner surface receiving and constituting a guide for the stem 9 providing a hollow externally threaded head 10 fitted within the internally threaded portion 7 of the bore whereby the head may be conveniently adjusted longitudinally of the barrel by proper manipulation of the stem 9, such manipulation being facilitated by a hand wheel 11 attached to the exposed terminal of the stem.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Serial No. 323,054.

The terminal of the bore of the barrel opposite the threads 7 is also enlarged and internally threaded to receive a nut 12 provided withan internal packing 13 and a cap nut 14L to prevent the escape of fluid from the interior of the barrel 5.

An inlet pipe 15 communicates with the restricted portion 8 of the bore at a point intermediate the screw threads 6 and the nut 12. r

The internally threaded portion 7 of the barrel is externally reduced and threaded to receive the internally threaded terminal of a hollow cap 16 having an internal flange 17 defining a trap chamber 18 for the reception of such foreign matter as dust and dirt and the like which is conducted to the sprayer to prevent its admission to the spraying ports of the barrel to be hereinafter more fully described.

In order that the sediment collected in the chamber 18 may be removed, a port 19 is formed at the terminal of the cap which is normally closed by a removable plug 20. The terminal of the head 10 is reduced as at 21 to provide an annular chamber between the inner surface of the barrel 5 and the head, and the terminal of the head is beveled correspondingly with the inclination of the valve seat 17 whereby the admission of liquid to the annular chamber is controlled.

The wall of the barrel 5 lying adjacent the head 10 is formed with a series of rela tively small perforations or ports 23 arranged upon a line extending spirally about the barrel and adapted to be successively uncovered as the threaded head 10 is advanced toward the inlet pipe 15 so as to control the discharge of liquid through the ports. The liquid entering the threaded portion 7 of the barrel 5 from the inlet pipe 1.5 finds its way into the interior of the hollow head 10 through oblique ports 2% and when it is desired to entirely cut off the discharge of liquid through the ports 23 the head 10 is adjusted, by proper manipulation of the hand wheel 11 so as to seat the beveled terminal thereof against the flange 17 and thereby prevent the admission of the liquid into the chamber between the frame terminal 22 of the head and the inner surface of the barrel 5.

hat I claim is:

1. A device of the character described including a hollow barrel provided with a longitudinal bore and having a portion of the bore internally threaded, said barrel having a series 01" discharge ports arranged in the wall of the threaded portion thereof along a line extending spirally of the barrel, and a controlling head fitted in the threaded portion of the bore and adjustable therein to successively cover or uncover the discharge ports according to the direction of rotation of the controlling head, said controlling head having an axial opening and oblique openings communicating with the bore of the barrel.

2 A device of the character described including a hollow barrel having discharge ports therein, a hollow cap connected with one terminal of the barrel, an internal flange carried by the cap providing an internal chamber adapted to receive and trap solid matter conveyed into the barrel by the liquid passing therethrough, and a controlling member adjustably fitted in the barrel for controlling the discharge )orts and engageable with the flange.

A device of the character described including a hollow barrel having discharge ports therein, a hollow cap connected with one terminal of the barrel, an internal flange carried by the cap provided with internal chambers adapted to receive and trap solid matter conveyed into the barrel for the liquid passing tl'ierethrough, and a controlling member having a longitudinal liquid conducting passage and adjustably fitted in the barrel to control the discharge ports, said controlling member being engageable with the flange to cut ofl communication between the interior of the controlling member and the space between the latter and the barrel.

i. A device of the class described including a hollow barrel provided with a longitudinal bore and having a portion of the bore internally threaded, said barrel having a series of discharge ports therein, and a controlling head fitted in the threaded portion of the bore and adjustable therein to successively cover or uncover the discharge ports according to the direction of rotation of the controlling head, one end of the controlling head being reduced in diameter to provide a space between the latter and the inner surface of the barrel, and an internal flange carried by the barrel engageable with the terminal of the controlling head for cutting oil communication between the interior of the latter and the discharge ports.

In testimony whereof, I allix my signature hereto.
